SciSpace

SciSpace is an AI research assistant built for academics, graduate students and R&D teams. It combines a paper search index of more than 280 million papers with tools for chatting with PDFs, extracting data into tables, generating literature reviews and drafting text with cited sources. The company says more than 9.6 million researchers use it.

Beyond search and reading, SciSpace bundles a set of writing and integrity utilities: an AI Writer, paraphraser, citation generator, AI detector and humanizer, plus a SciSpace Agent and a Biomedical Agent that string several of these steps together. Usage is credit-based, so heavier tasks like deep literature reviews draw down a monthly allotment.

It suits PhD students, postdocs and corporate researchers who want one workspace for finding, reading and writing about papers. Casual users who only need to summarize a single PDF may find lighter and cheaper options enough.

SciSpace uses a subscription-plus-credits model. The official pricing page we could read showed the plan headline and a 24-hour money-back guarantee but not the dollar amounts, so the figures below come from a third-party tracker (CostBench, last verified October 2026) and should be confirmed on scispace.com/pricing before you buy. That tracker reports no permanent free tier or trial.

Reported paid tiers: Premium at $20/month or about $12/month billed annually ($144/year); Advanced at $90/month or about $70/month annually ($840/year); and Max at $200/month or about $160/month annually ($1,920/year). Annual billing is said to save roughly 20 to 40 percent depending on tier.

Enterprise pricing is custom. Usage is credit-based and monthly credits do not roll over; add-on credits and services such as English editing or journal submission cost extra. Several user reviews describe credits running out faster than expected, so starting monthly before committing to an annual plan is sensible.
